                                 Permanent magnet synchronous motors
                        with integrated electronic drive for swimming-pool pumps

                                educing CO2 emissions is one of the major challenges we face in

                        R       saving the environment. Motorised applications account for a very
                                significant proportion of energy consumption.
                        The use of variable speed and optimisation of mechanical systems are the main
                        routes to achieving maximum savings.


                                              ♦ DYNEO®, INNOVATION:

                        DYNEO®, at the cutting edge of commercially-available variable speed
                        technologies, brings together all LEROY-SOMER’s permanent magnet
                        solutions for drives and synchronous motors.
                        Part of the DYNEO® offer, the LSRPM-VMA series, the cost effective, high-
                        performance variable speed solution, uses the most up-to-date design
                        techniques. This new motor-drive set fully meets the expectations of users and
                        integrators of swimming-pool filter pumps and swims against the tide for
                        swimming-pool applications:

                          -   IP 55 construction in accordance with IEC 60034
                          -   Power rating from 0.75 to 3 kW
                          -   Speed from 1 to 3600 rpm
                                          ♦ DYNEO®, ENERGY SAVINGS:

                       By reducing rotor losses, the permanent magnet rotor technology greatly
                       improves efficiency, specific output power as well as motor service life.

                       At rated speed, LSRPM-VMA motors in the DYNEO ® range have significantly
                       better efficiency than high-efficiency induction motor-drive sets.

                       This difference in efficiency becomes even more significant when operating
                       below rated speed, which is by definition the case in variable speed
                       applications!

                       Additional advantage of the LSRPM-VMA motor-drive set: the ability to rotate
                       faster than an induction motor, which allows:

                         -   the motor speed to be adapted to that of the driven pump,
                         -   the pump to be driven at its highest hydraulic efficiency point.

                       The return on investment time compared to a conventional solution is very
                       often less than 12 months.


                                      ♦ DYNEO ®, INTERCHANGEABILITY:

                       The LSRPM-VMA series is completely interchangeable with single or three-
                       phase asynchronous motors traditionally used in this application.

                       Stainless steel shaft ends and aluminium flanges are adapted for various
                       existing pump housings.
